Abstract

The electric field in cavity accelerates charged particles and magnetic field of magnets changes the direction of these particles in cyclotrons. In order to establish the electric field inside the cavity, a noiseless radio frequency (RF) signal should be generated, amplified and sent to cavity. The resonant frequency of the cavity could be changed by temperature variation. Variation of resonant frequency will cause reflected power from the cavity. in this work the low level RF circuits with task of signal generation, phase and frequency Adjustment, cavity resonant frequency Adjustment, protection of the RF set from the reflected power and stability of RF system was designed
